RJ Cooper — Osmosis, Oners, and Editing Three Movies at Once

James's longtime editing partner and secret weapon RJ Cooper finally sits down in front of a camera. A USC film school grad who started out designing posters for Batman Begins and Spider-Man, RJ has cut the bulk of James's directing filmography — Survive the Game, Hot Seat, Fortress, Darkness of Man, The Workout, Boris is Dead, and I Have Proof — and the two have developed a creative shorthand that borders on telepathy. This one gets into the real craft: how editors read footage, fight for the film alongside the director, and keep the heart of a movie alive when producers start circling.

Key topics & highlights:

• How RJ and James developed their editing language across seven-plus films — and why the first cut keeps getting closer to what James actually wanted
• The frame-blending trick born on The Workout and the Star Wars–style wipe transitions RJ snuck into Boris is Dead over James's objections (and won)
• Hot Seat's unique challenge: building fake computer screens for Kevin Dillon to react to and fighting for every stock helicopter shot
• Why The Workout's extreme multi-camera chaos (15 cameras, cell phones, angles James didn't know he had) ended up changing the way both of them shoot and cut forever
• Editing three feature films simultaneously — and how he keeps the worlds straight
• Reading a director's signature: James = performance + action + dark humor; Matt Eskandari = relationships; John Keyes = women against impossible odds
• Actors who gave him gold he had to leave on the cutting room floor: Antonio Banderas and Alice Eve
• RJ's most panic-inducing job: Hot Seat, with its blank monitor problem
• His first feature: Game of Assassins shot in China with Bai Ling
• Three Bruce Willis films with Matt Eskandari
• Pre-production involvement on Boris is Dead — hired before cameras rolled, suggesting shots and knowing the film needed heavy needle drops from day one
• Music as craft: temp tracks (Dark Knight, Interstellar, always Sicario), playing the edit like an instrument, and using his wife as a fresh-eyes test audience
• AI in post: Night Driver as a real-world test case, AI ADR via ElevenLabs, the color-space limitations of AI-generated visuals right now, and why storytelling with a point of view is the only real moat
• RJ's directorial ambitions: sci-fi (loves Denis Villeneuve), Westerns (already collecting sound effects just in case), and James's on-the-record promise to produce his first feature
• James's $7,000 first-film program and the indie model (No Stars, $200K budget, $4.5M at AMC with no P&A)
• UFOs, Tesla life, Gerald the Dolphin, and alien cinema (Blurp 3 is apparently the masterpiece)
